Abstract:
This tape contains a monthly archive of 4 satellite-derived SST field accumulation files 1) 500-km global field at 5 X 5 degree latitude/longitude resolution between 70S and 70N. This field is produced daily by averaging gridpoint temperatures in the 1 degree latitude/longitude SST field file; 2) 50-km regional field at 0.5 X 0.5 degree resolution within the region 5N-53N and 100W-52W. This field ... is produced weekly by analyzing all the SST observations obtained during the previous week; 3) a second 50-km regional field covering 15N-63N and 145W-97W; and 4) a third 50-km regional field covering 15N-63N and 170E-142W.

This tape is a 9-track, 1600 bpi, unlabeled, odd-parity, binary tape produced on an IBM 360/195 computer. The tape has 5 physical files separated by physical end-of-file marks. The first file has only 1 record which contains information about the data on the tape and serves as a header file. The second file contains 36 500-km daily fields organized chronologically. The first physical record of the second file is a directory record pointing to the beginning of each of the 36 fields. Each field consists of 30 logical records of 2044 8-bit bytes per record blocked into 5 physical records of 12264 8-bit bytes. Thus there are 1+(5x36) = 181 physical records in the second file. Since there are 36 fields, data will span somewhat more than one month. The third file contains the first 50-km regional field archive. There are five weekly fields organized chronologically. The first physical record of the third file is a directory record pointing to the beginning of each of the 5 fields. Each field consists of 98 logical records of 2744 8-bit bytes per record blocked into physical records of 10976 8-bit bytes. There are a total of 1+(5x98) = 491 logical records blocked into 123 physical records in the file. The fourth and fifth files are identical to the third file in organization.
